The three-minute video starts with a short time-lapse of the build, followed by setting up the ill-fated Porsche on a remote-controlled mini conveyor belt, with a glimpse of the crash wall ahead.
With a speed of 45km/h (or about 400km/h in the real world), the 1:8 scale vehicle hurtles towards the barrier.
Just before the car impacts, the video goes into slow motion, set to a famous piece of classical music.
Most of the 2704 pieces of the Lego set fly through the air in spectacular fashion.
For anyone who has spent hours or days building one of these models, it may be excruciating to watch. But, in a weird way, it's somewhat satisfying - perhaps because it's not the $387,300 real deal.
“The result was impressive and different than expected. The chassis of the car had no problems with the high-speed impact, and there were very few damaged pieces on impact. It was almost exclusively the click connections between the components," said ADAC.
